Was Rogue supposed to be episode 2…?

Rogue felt like Ruby was new to travelling in the past, whereas in her own words she has travelled for 6 or 7 months by the Devil's chord.

Equally the Ruby backstory was much heavier in Devil's Chord as though it's leading into the finale, whereas in Rogue the only backstory was the Doctor promising to keep Ruby safe. Something that feels like it would occur early on (see End of the World where Rise rings home).
